Develop the post and cap as a pair
A branded fence system needs repeatable interfaces across panels, posts, brackets, and caps. Begin by defining which post families the program includes. A hollow square post with a formed cap and a Y-profile wire-fence post should have separate drawings and accessory lists.
EONE can review customer drawings for custom dimensions, materials, finishes, and interfaces within its posts and caps range. OEM and private-label supply can include coordinated branding and packaging. Every proposed design remains subject to manufacturability review, agreed quantities, and project-specific terms.
Make the post drawing complete
Identify section shape, outside dimensions, wall thickness or profile definition, steel grade, overall length, straightness requirements, and attachment locations. Where mass per length is relevant, specify its role in inspection rather than treating it as a substitute for material and section data.
For a flanged post, show base-plate dimensions, orientation, hole centers, weld details, and any approved drainage features. The responsible designer should define structural requirements and the supporting foundation or substrate. EONE's manufacturing review does not automatically provide site engineering or an anchor design.
- Separate line, end, corner, and gate-post part numbers.
- Identify finished dimensions and the tolerance required at bracket interfaces.
- State which holes and attachments are factory-made and which field work is permitted.
- List caps, brackets, bolts, and anchors individually, including excluded items.
Specify the cap from the mating opening
The cap drawing should define internal dimensions, corner geometry, rim depth, top shape, thickness, retention, and finished clearances. A nominal size name alone is inadequate, particularly when inch and metric profiles are mixed. Define the post that the cap must fit and the method used to verify that fit.
Agree whether caps are removable, factory-attached, or supplied separately. Review the resulting water-management and maintenance detail. A cap should not be advertised as waterproof, impact-protective, or structural without evidence for that particular function.
Resolve coating before fabrication
State the coating route, pretreatment, color reference, gloss, appearance limits, and handling protection. If an assembled hollow post will be hot-dip galvanized, review venting and drainage before welding it closed. The American Galvanizers Association notes that square and round tubular assemblies require geometry-appropriate details; a detail for one should not simply be copied to the other.
Keep manufacturing venting separate from the finished installation's drainage requirements. Coordinate both on the approved drawing. For a powder-coated finish, review post and cap samples together and check that coating buildup does not prevent assembly.
Approve samples, labels, and reorder records
Request samples or an agreed first article to review section fit, cap seating, bracket alignment, base-hole orientation, finish, and packing protection. Document the accepted drawing revision and measurements. Separate this dimensional approval from any required structural or corrosion testing.
Provide authorized artwork, logo placement, bundle labels, carton marks, barcodes, and packing quantities. EONE can coordinate branding across long-post bundles and cap cartons so receiving staff can match the parts. Avoid unsupported certification or service-life statements.
Freeze material, section, finish, cap interface, accessory list, inspection plan, and packing specification for repeat orders. MOQ, tooling, testing, packaging costs, and timing are agreed per project. Send the OEM post-and-cap brief with drawings and forecast quantities.
